For all I know (and it's not even a product of the company that pays me), it's a fine device.

I'm pretty sure that a HackRF's oscillator should be just as good as the one of an RTL-dongle. But an RTL dongle in TV reception mode does automatic frequency correction.

Anyway, real-world receivers always continously adjust frequency, because in this world, no two oscillators are the same, physically. > > > Version information > > *Operating system*: > debian os , gnuradio 3.7.12,linux > > why hackrf one not can received ? it has weakness in receiving? weak > receiving can be related to ppm ? > > please help, any idea??? it can be related ADC?HackRFone has poor > receiving why? > Yeah, come on, describe the problems you're having, and what you tried to solve them.
